3 LINE MESH

 

Description: This function generates elements in an area defined by 3 lines (line direction is not important).  The lines defining the area do not have to intersect (an open area is possible). Elements are included in the CURRENT PART.  The CURRENT PART should be verified before proceeding with this function.  Two mesh patterns are available for 3 Line Mesh (triangular shape).  DSI generates the triangular elements and allows the user to position them on the model.

 

Usage:

 

1.  DSI prompts:

>   SELECT 3 LINES

  LINE SEGMENT allows the user to combine a broken line while selecting lines for the 3 LINE MESH function as in the COMBINE LINE function in the LINE section.  The user must select this option before selecting the desired lines for 3 LINE MESH.

   The user may check the line(s) prior to executing this function by using SHOW LINE in the LINE section.

 

2.  Once the user selects the desired lines, the prompt will read:

>   ENTER MESH TYPE: 1 OR 2

    

 

?   1-TRIA. AT CORNER

 •   Triangles are concentrated in the vertex of the first two selected lines.

                                   >  ENTER NUMBER OF ELEMENTS: N1, N2, N3

                                2-TRIA. ALONG EDGE

 •   Triangles are concentrated along the third selected line.

                                   >  ENTER NUMBER OF ELEMENTS: N1, N2, N3

•   DSI accepts only one entry, as each side has the same number of elements.
